The drugs were found during searches by the Kalamazoo Valley Enforcement Team and Kalamazoo Public Safety’s SWAT Team at residences in the 2200 block of South Burdick Street and the 600 block of Jefferson Place, and a business in the 1000 block of West North Street, according to a news release issued Friday by KVET.

Crack and powder cocaine were found at the residence on Burdick Street, police said. Crack cocaine was found at the North Street business.

At the residence on Jefferson Place, police said the drug unit came across “an aggressive, unlicensed pitbull” in a stairwell and an officer fired at the dog in self-defense. The dog was struck once and retreated into the house’s basement, police said, and a Kalamazoo County Animal Services officer later took custody of the pit bull.

Inside the residence, the drug unit found “a large quantity of heroin, marijuana and an unregistered handgun,” according to the news release.

Police said two Kalamazoo men, both 38, were arrested in connection with the drug raids. Their names were not released Friday.

One of the men was arrested on suspicion of possession with intent to deliver crack and powder cocaine. The other man was arrested on suspicion of possession with intent to deliver heroin, possession with intent to deliver marijuana and weapons offenses.
